MARKER Eon PLANTEES.

Specification of Letters Patent.

Patented Nov. 28, 1916.

'Application filed July 9, 1915. Serial No. 38,957.

To all whom t may concern Be it known that I, EMIL J. PETERSON, citizen of the United States, residing at Albion, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Markers for Planters; and I dofhereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in marker bars for planters and means for manipulating the same. u

My device relates more particularly to that class of markers in which a single marker bar is pivotally attached to the rear end -portion of the planter frame, the parts `being so arranged that when'the machine istraveling in one direction across the eld the marker bar projects substantially at right angles to the machine lframe and marks the ground for the neXtrow, land then when the machine frame is turned at the end of the field, the marker barjisraised and turned over to operate on the opposite side of the machine.

The object of my invention is to Provide mechanism for use with 'said marker, which will assist the operator of the planter in turning said -marker bar whenit is necessary to doso.

A further object of my 'invention is to provide a device `of this class which will be simple and durable and of inexpensive construction and which may be applied to planters nowjin use. v

With these and other objects in view, my invention consists in certain novel features of construction and combination of Vparts as set forth Vin the following specification,

illustrated Vin the accompanying drawing,

and more particularly pointed out in the appended claims.

Referring to the drawings, Figure 1 is a top plan view of a. planter showing the marker bar in projected or operative position and my improvement connected therewith.A Fig. 2 is a front elevation of my appliance, showing the position of the parts when the marker bar is in lowered position on the right hand side of the planter. Fig. 3 is a similar view, showing the position of the parts when the marker bar is in lowered position exi-the opposite side ofjtliiernahiae.

F ig. 4 is a similar view showing the position of the parts when the marker bar is in raised or vertical position. Fig. 5 is a vertical sectional view of my improved marker bar lifted, taken on line 5-5 of Fig. il. Fig. 6 is a rear elevation of my appliance taken in the-direction of the arrows 6 6 of Fig. 5, and having the rear half of the gear casing removed.

In the drawings A denotes the main frame of a planter which is mounted upon the supporting wheels B in the usual Ymanner and is provided with the usual seat C forl the operator.` These parts are all of ordinary construction, and my attachment applies equally as well to machines of different structures. The# marker bar hereinafter ,describedv is attached to the planter on the rear bar of the frame A. u

The reference numeral 1 designates a bracket which is secured to the rear bar of the frame A byv a single bolt 2 that passes through a thimble 2a of said bracket. The bracket has its upper end formed in the shape of al half casing and a plate 3 is secured to said half casing by'means of bolts 4 to form a complete housing. Rigidly secured to a hollow axle 5, which is loosely mounted ,in the housing and-is retainedgbyV a bolt 5a,

lface of the gear '7, and pivotally secured vbetween the ears by means of a bolt9, is the inner end of the markerA bar 10,.A The markerbar 10 carries at its outer end the usual disk marker 11, and a rope 12 connects the outer end with the front of the planter. A

Rigidly secured to the .aXleri and on the .exterior of the bracket 1, is a crank 13 which is pivotally connected to the inner end of a coil spring 14C. A bracket 15 is rigidly secured to one of the side bars of the frame A and a strap 16 having a screw threaded shank 17 which passes through an aperture in said bracket 15, is secured by means of a nut 18.V Notches 19 are provided in said strap and the cuterfend if the eel spring il may he made to engage either oi said notches, thereby varying the tension of said spring lll.

A chain 20 connects the marker bar 10 with the seat C of the driver or operator, and is used for elevating the marker bar.

The operation of my device is as follows: Assuming that the marker bar is in-raised or vertical position, as shown in Fig. 4,- where it is held by a slight tension on the spring' l-l, and that the operator desires to lower the bar to operative position on the right hand side of the machine. To accomplish this he presses downwardly on the marker bar, which is moving against the tension of the spring 14C, until the gear 7 has moved slightly more than one-quarter of a revolution and the gear 6 has moved slightly more than one-half a revolution, or until the crank 13 has passed its horizontal center at the side opposite its initial position, as shown in Fig. 2, when the operator may release the bar which obviously will be forced downward to the limit of its movement by the spring 14, acting on the crank 13. It will thus be yseen that after the crank 13 has passed its horizontal center on the left hand side of the bracket l, the-'spring 14 through the medium ofV the crank and gears has a tendency to forcethe outer end of said marker bar constantly'toward the ground, thereby insuring a visible mark. When the machine has reached the end of the field and the operator wishes to raise the marker, he grasps the chain 20 and draws upwardly until the outer end of the crank 13 again passes its horizontal center, when the spring 14 will raise the bar into vertical position. After turning the machine, the bar 10 is pressed down to operate on the ground to the left of the machine. lVhen the bar is pressed toward the left the crank moves rst downwardly and then upwardly until it again passes its horizontal center, at which time the spring will move the bar the remainder of the distance toward the ground and maintain the ysame incontact therewith as heretofore described.

VFrom the foregoing it will be seen that I have devised an appliance which will materially assist the operator of a planter in raising the marker and bar, thereby relieving him of the strain incident hitherto to such operations and at the same time enables him to manipulate the marker bar more expeditiously. It will also be appar- -ent that my device may be applied to machines now in use, in a short period of time and at a minimum expense.

`What I Vclaim Yand desire to secure by Letters Patent is :-V

l. An auxiliary appliance for raising the marker bar of planters, comprising an automatic Vraising means, and gearing provided between said automatic raising means-and said marker bar, said means exerting a downward pressure on the outer end of said bar when said bar is in lowered position.
